Detailed Description
The invention will be further explained with reference to the drawings and the detailed description below:
as shown in fig. 1 to 4, a glass fiber reinforced plastic desulfurization tower comprises a tower body 1 and an induced draft fan 2, and further comprises an induced draft pipe 3 for connecting the tower body 1 and the induced draft fan 2, wherein the cross section of the induced draft pipe 3 is circular, a cyclone 34 is arranged inside the induced draft pipe 3, the cyclone 34 has the function of changing the airflow direction in the induced draft pipe 3, so that tail gas impacts on the inner wall of the induced draft pipe 3, water is gathered on the inner wall of the induced draft pipe 3 and slides to the bottom of the induced draft pipe 3 to enter the induced draft fan 2, an air outlet pipe 33 is arranged at the bottom of the induced draft pipe 3, the air outlet pipe 33 is a bent pipe with an arc, one end of the air outlet pipe 33 is connected with the inlet of the induced draft fan 2, the other end of the air outlet pipe penetrates through;
the cyclone 34 comprises a fixing ring 341, a plurality of air deflectors 342 and a flow guide cover 343, the fixing ring 341 is a circular ring body with the diameter consistent with the inner diameter of the air guide pipe 3, and the fixing ring 341 is fixedly connected with the inner wall of the air guide pipe 3; the flow guide cover 343 is a truncated cone with a small upper part and a large lower part, the air deflector 342 is connected with the top surface of the flow guide cover 343 and the inner side surface of the fixing ring 341, the air deflector 342 is an arc-shaped plate body, and the air deflector 342 inclines upwards and forms an included angle with the horizontal plane.
